u Application filed January 18, 1899. Serial ll'o- 2,691. lllo modell) Q 7 l I 1 Be it known that I, W1LL1AM QW1NF acitizen of the United States, residin g at Warren, in the countyof Trumbull and State of,

Ohi'o,,have invented} certain new and useful Improvements in'TubularLanterns and ldo. declarethat the fo llowingis a full, clear,',and exact description of thein'vention, which .Will

enable others skilled in the art to which it ap pertainsto make anduse the same.

v My invention relates to tubular lanterns and the object'of the invent-ion is to provide means whereby the globe canbeeasily raised pointed out inth'efclaims.

O are carrying and guide wires for the globe, connectedwith the globe-supporting plate D at the bottom and-with the canopy E at the top. The'conneotions with the'canopy and the plate D are rigid, as hereshown, sothat, in a sense, the Wires O, plate' D,and-canopyE lELD, I

l are one} rigid strnctureand frame adaptedtomove lZOgBii'hGfflSOllE) and carry and support,

the globe.- "The'fsaidwiresU are eachs'hown as bent inward at right'angles.attheir loweri V 5 ends and forming horizontal portions 0', which eitherengage directlywith,the'plate Dorareextended more or less aroundtheedgeof said j pl'ategf'Q ne of-said iwiresjjisalsobenthigher,6o ,7

up to form an oifset or shoulde'r'o, andfthe I tu'b'ulai frame or tubesAhave guides a 01 their inner side, about midway theirheight,

which serveto confine andguide the wires 0, 1

especially'whenthe globe isr-aised and lowcred. As many such guides o may be used as are; deemed best; but two. s'uifioe to'keep' the globe and frame in place, and they serve especially when the globe is being raised and lowered. l

down movem'entsof the globe contemplated by myinvention' asimple mech anism isrequired, consisting oft-he substantially elbo w-. shaped member G, p-ivotally connectedat its top on "the shoulder o and having a segmentals'lotjg infits lower portion engaged and work- New, in order toeffect the direct .up-and' ing'on thehorizontal port-ion coffthe'side wire. Then. in order to utilize said part G in the raising and lowering of the'globe I employ, a doublebell-crank lever H, Which-is pivoted in andat one end of the'segment-slot g.

In operation when the globe is to be raised on the. side ofthe tube Aiand has a; handle portion outside and its inner portion'h. en; gaged in the part G at or near the angle therethe elbow G is swung by lever 11 first the full slot-as shown in dotted lines',: Fig. 4:. This movement of elbowG and its slotgisfar enough forthe bell-crank lever'H to describe theextren' e of its outward movement. From this point the movement is upward and inward'until the half-circle of movement has been described and theparts are brought to full lines, Fig. 4. Here the bell-crank is shown as swung a little past the center to lock the parts. I In likemanner when the globe is down the lever swings past the center a little and locks the globe-frame in its lowered position, -'Referr ing to Fig. 4:, it will be seen that the elbow occupies the samefrelation to the parts as it does in Fig. 1, and one is the raised and the other is the loweredposition. Meantime to get either position from the other the elbow must traverse the full length of its curved slot or channel twiceback a'nd'fortll because it has just length enough to accommodate itself to the successive quarter-turns of the bell-crank lever.

Obviously the foregoing arrangement, of parts could be inverted and serve identically the same purpose-that is, the part G could be pivoted on the horizontal wire and the segment engaged on shoulder c and the lever H be moved up correspondingly. The same half-rotation of lever H would be effected with the same results, and hence it is immaterial which way the parts are arranged.

Another novel feature of construction is the canopy. E and the shield or collar L, connected therewith. The canopy has an oblong hole in its center for the central draft-tubeK' of the lantern, and the collar L has a central free but round opening for said tube. Keepers 70 on the canopy confine the collar L, and the construction and arrangement of these parts are such thatthe canopy has a limited tilting movementfor example, about as seen in Fig. 6.

The side wires 0 have spring enough to allow'this to be done even though they are rigidwith and not pivotallyattached to the canopy. When the globe has been removed, the spring of the wire presses the canopy back to centralposition again.

Meantime the plate L serves as a shield to the oblong opening in the canopy and effectually closes the canopy about the central tube K.

In order that the handle M maybe held upright, I have extended the end m thereof inward horizontally over the horizontal portion of the tube A and provided said tube with a depression, Fig. 2, into which the extension m springs and locks suff ciently to sustain the handle, as in Fig. 1.

It will be seen that when the arm of the lever H is horizontal the segmental slot g will have reached its outer limit, so that any further movement of said lever will cause a re trogade movement of said slot.

What I claim is- 1. In tubular lanterns means toraise and lower the globe comprising the frame, a pivoted lifting part engaged at two points on said frame, and a pivotedlifting-lever connected with said pivoted lifting part, substantially as described.

2. The tubular frame and the globe-frame, in combination with a member pivoted at one end on the globerfrarne and constructed at its other end with a curved channel to swing on said frame within fixed limits, and a liftinglever journaled on the adjacent. air-tube and connected with the swinging end of the said member to lift and lower theglobe-frame, substantially as described.

3. The air-tubes and the globe and its care rying-frame, in combination with a rotatable lifting-leverjournaled on one of the air-tubes and a swinging part pivoted at one end on said frame and having a curved slot at its other. end working on. said frame, and the said lifting-lever connected at its innerend with said swingingmember, substantially as described.

4. The tubes and the glohe frame, in co1n-.

b'iuationlwith a rotatable lifting-lever on one of said tubes, and a lifting member connected near its lowerend with said lever and pivoted on the side of the globe-frame atthe opposite end from its engagement with the lifting-lever, said. member having a segmental slot within which is confined a substantially horizontal portion of the globe-frame, substantially as described.

5. In a lantern, the tubular frame and central draft-tube, in combination with the canopy having an oblong opening aboutsaid draft-tube and a plate engaged on the under side of the canopy and extending aroundthe draft-tube to close the oblong opening in the a 1opy, substantially as described.

6. The tubular frame having a depression in its upper portion, in-combination with the wire bail looped around saidfrarne and having one of the ends of the wire extending outside of its loop around the frame and bent to a substantially horizontal position to lie normally in said depression, substantially asdescribed.
